Matchup analysis
Before kickoff our model projected Idaho 31.9, Southern Utah 30.8 at Kibbie Dome in Week 8. That is a genuine toss-up: Idaho wins about 53% of the time by our estimate, with a projected margin of 1.1 points and 62.6 combined points. Tags: coin flip, leans high scoring.
Southern Utah is 3-4, scoring 32.3 and allowing 33.4 points per game (-1.1 per game). Idaho is 2-5, scoring 29.7 and allowing 39.3 points per game (-9.6 per game).
College football is noisy: even a well-rated projection misses the final margin by about 14 points on average. Based on how real results have scattered around our numbers, the final margin should land somewhere between Southern Utah by 21 and Idaho by 24 about 80% of the time.
Idaho gets about 2.1 points for playing at home. That home edge is the difference: on a neutral field Southern Utah would be favoured by 1. The game is on ESPN+.
Result: Southern Utah 28, Idaho 31. The model had the right winner; the margin was off by 1.9 points and the total by 3.6.
